Why is gold used in electronics instead of silver?

Gold has a wide variety of uses in electronics because of its unique physical and chemical properties: It has excellent resistance to corrosion and oxidation, whereas silver tarnishes in atmospheres containing minute traces of sulphide.

Is gold or silver used more in electronics?

Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has much higher corrosion resistance. Because silver tarnishes, it is less desirable for high frequencies because the exterior surface becomes less conductive.

Where is the gold in a computer?

Motherboards and Circuit Boards Motherboards – the biggest circuit boards inside both laptops and desktops – often contain the “mother lode” of gold in used computers. Their edges have gold contacts and connectors where wires slide on. You will also find thin layers of gold applied to motherboards’ surfaces.

Why is gold so important to us?

The metal is abundant enough to create coins but rare enough so that not everyone can produce them. Gold doesn’t corrode, providing a sustainable store of value, and humans are physically and emotionally drawn to it. Societies and economies have placed value on gold, thus perpetuating its worth.

How much gold can you recover from a computer?

The answer varies depending on the e-waste recycling source and computer board ore. We believe it conservative to say with today’s gold price, over $10 of gold gets layered in an average computer.
